If you're buying for a newly diagnosed T2, this is going to be pretty confusing, because you are likely to be getting plenty of official advice to keep fat (and especially saturated fat) low, and to maintain a balanced diet, of wholegrains, fruits and veg.
It's going to be especially difficult, because you also may not have the same response to the same foods as your husband.
@lovinglife is totally on the money though, and lots of us here will attest. Fundamentally, type 2 diabetes is about someone struggling to cope with sugars and starches (which turn into sugars). Low fat alternative products are almost always made that way by replacing natural (and perfectly healthy) fats with heavily processed starches, which cause our blood glucose to rise.
Feta, Hallumi, Cheddar, Brie, pretty much all cheese is great, but should be full fat (and recognise that to mean "no added sugar")
